The primary objective of this book is to provide a review of techniques available for the problems of wave propagation in regions with uneven beds as they are encountered in coastal areas. The view taken is that the techniques should be useful for application in advisory practice. However, effort is put into a precise definition of the underlying physical principles, so that the validity of the methods used can be evaluated. Both linear and nonlinear wave propagation techniques are discussed. Because of its length, the book comes in two parts: Part 1 covers primarily linear wave propagation, and Part 2 covers nonlinear wave propagation.

In Part I of this report, a time dependent form of the reduced wave equation of Berkhoff is developed for the case of water waves propagating over a bed consisting of ripples superimposed on an otherwise slowly varying mean depth which satisfies the mild slope assumption. The ripples are assumed to have wavelengths on the order of the surface wave length but amplitudes which scale as a small parameter along with the bottom slope. The theory is verified by showing that it reduces to the case of plane waves propagating over a non-dimensional, infinite patch of sinusoidal ripples, studied recently by Davis and Heathershaw and Mei. We then study two cases of interest--formulation and use of the coupled parabolic equations for propagation over patches of arbitrary form in order to study wave reflection, and propagation of trapped waves along an infinite ripple patch. In the second part, we use the results of Part 1 to extend the results for weakly-nonlinear wave propagation to the case of partial reflection from bottoms with mild-sloping mean depth with superposed small amplitude undulations. Keywords include: Combined refraction-diffraction, Linear Surface Waves, Shallow and intermediate water depths, and Wave reflection.

This book is an expanded version of The Applied Dynamics of Ocean Surface Waves. It presents theoretical topics on ocean wave dynamics, including basic principles and applications in coastal and offshore engineering as well as coastal oceanography. Advanced analytical and numerical techniques are applied, such as singular perturbations. In this expanded version, three chapters on recent developments have been added. The first is on multiple scattering by periodic or random bathymetry. The second is on Zakharov's theory of nonlinear wave fields with broad spectra. The third is an extensive discussion of powerful numerical techniques for highly nonlinear waves. Other new topics include infragravity waves, upstream solitons, Venice storm gates, etc. In addition, there are many new exercises.Theory and Applications of Ocean Surface Waves will be invaluable for graduate students and researchers in coastal and ocean engineering, geophysical fluid dynamicists interested in water waves, and theoretical scientists and applied mathematicians wishing to develop new techniques for challenging problems or to apply techniques existing elsewhere.
